Great 10440 IMR battery. 10440 is AAA size. Note the voltage is 3.7V so your device must be made to handle the higher voltage (Alkaline AAA are only 1.5V). These are somewhere between a flat top and button top, there is a bit of a button top but it's not quite as pronounced as a normal button top. Efest does not make the full button top anymore.

As always, you can trust Liion Wholesale to have tested random samples from each and every batch to make sure all the batteries are fresh and genuine. Anyway we have an agreement with Efest themselves and buy only manufacturer direct for these so the chances of issues are small, but we test anyway. You won't get that with most suppliers.

Batteries are sold individually.

If your battery is damaged or defective on arrival (will not take its first charge, or has issues with its first cycle), please let us know within 14 days of receiving your order and we'll make it right. Please read our complete store policy on defective products here for more information and to see if you're eligible.

All rechargeable batteries have inherent risks under any circumstance. Use caution with working with li-ion batteries (lithium-ion), LiPo (lithium ion polymer), and any rechargeable cells (together "rechargeable batteries"), as they have dangerous charging characteristics and are known to explode or burn if mishandled. A purchaser and user of rechargeable batteries should educate themselves on rechargeable batteries, especially as to charging, discharging, assembly, and storage. Learn more about proper storage and care for rechargeable batteries here. We are not responsible for any damage caused by the misuse or mishandling of rechargeable batteries.

Properly dispose of all battery cells and chargers in accordance with local laws and mandates (if you're unsure, contact your local municipality)

If a rechargeable battery overheats, hisses, or bulges, immediately quarantine the battery from any combustible materials - ideally, take the battery outside

If a rechargeable battery catches fire, the FAA recommends pouring water or soda on the battery and surrounding areas - ideally, use a foam extinguisher to quell the fire

Great Battery

I have a custom made flashlight that uses this volt and sisize battery. There are many available other suppliers but I am leery if they are authentic. Llion has consistently provided excellent products as well as service. When I saw they were on clearance I bought enough to last me a while. I hope they are not discontinuing this battery or size.

What device/application do you use this with?Custom made flashlight, one cell ... made for this voltage.

Outstanding Product & Service

First of all the product is genuine and not a counterfeit . Has a scratch off that can be checked directly to the manufacturer. The product holds the charge and works better than other brands and chemistry that I have used in the past. Besides all of that, LiiON Wholesale has excellent service. Great combination.

Hi Walter - thank you for contacting us. I'm very sorry you received the wrong item - we had an issue with the stock level on this product when you placed your order, and it was actually out of stock when you ordered it (the quantity was artificially high). Our shipping team should have caught that and alerted us so we could reach out to you. I'm going to go ahead and refund you now for the 10440 you purchased (but did not receive). If you can't use the 14500 our team shipped instead, please let us know and we'll arrange to send a prepaid return envelope. Hopefully you do have a device that takes a 14500, in which case, please keep it and make use of it "on us" as a small token for the inconvenience. Please don't hesitate to contact us if there is ever a problem with your order - we'll do our best to make it right.
